We’re pleased to hear that Mr. Westrup, that’s how it should be!
The special circumstance in Linne is the big amount of slurry that is digested. The slurry of approx. 500 cows is around 90% of the input. Apart from that manure, fodder rests, green rye and grass silage are used. Approximately 75% of the produced gas comes from slurry and manure, which occur on the farm anyways.
We installed a pipe connection to the barn so the biogas plant is automatically supplied with 50-60 m³ of slurry per day.
In this way we reduce environmentally relevant methane emissions and instead get the energy from the slurry. After the fermentation process the digestate which is high-quality fertiliser, is land applied and by that the use of mineral fertiliser is reduced. With their biogas plant in Linne the family Westrup therefore supplies climate friendly and sustainable energy with low substrate costs and without further increasing the competition for renting land.
No wonder, little Isabel considers her daddy really clever, isn’t it?
